tone, have invented certain new and useful Improvements in Street. andHighway Snow-Cleaning Machines; and I do declare the following to bee.,full, clear, and exact description of the invention,- such as will. Ienable others skilled in the art to which it appertains to make and usethe same.

. This invention relates to the class of excavating, and more especiallyto those machines which include a plow and a carrier; of the same is toproduce a snow-cleaning machine for use on streets on highways and bymeans of Which'the snow and ice will be scraped or plowedfroni thesurface, carried upward, by a suitable 2o elevator, and then deliveredat eitherside of the machine either back onto the street or highway orinto a vehicle .which may he driven alongside. r

This and other objects'are carried out by 1'23 theconstructionh'ereinafter more fully described and claimed, and as shownin the drawings wherein- ,Figurel is a. side elevation of my improvedmachine; Fig. 2 is .a plan view there- 89 f Fig. 3'is an enlargedtransversesection taken on the line 3-3 of Fig. 1; F g. =1. an

iacl e; for han be possioleeespecially if another form of plow be era--I make this statetion thereof may be indulged in without sacrificing thegeneral principles involved. ile Ishowland do prefer a gasolene enginefor driving the various belts, it is .ossible that some other motivepower might e employed. Soalso with the means suggested below forpropelling the entire machine, for whereas I have suggested that itmight be driven by horse course possible that if the motor were largeenough the horses could be omitted and power taken from the motor topropel the machine. On this understanding it will be clearthatninchoft-he following description and the corresponding illustrationin the drawings, is given for faepurpose of setting forth the preferredvembodiment of my machine, rather than because the details shown anddescribed are necessary to its successful operation. I

The vehicle or support illustrated in the drawings herewith. sled whichis shown as comprising a main longitudinal beam '1 having a cross head 2at its front end and runners at the extremities single runner 4-beingpivotally mounted as atv 5 beneath the rear end of the beam andpivotto steer the vehicle by In fact, if the vehicle be propelled byhorse power it; may be steered by. directing the on the cross head 2 isalmovable frame 7 which extends forwardof the foremost runners 3 or theforemost truckof the \"fiillClG and carries zit-its front corners twoadjust able s11pports,2lieieiz1. shownas rulm'ers S which are. pivotedat one end as at 9 beneath the frame. and slotted in their. other endsas power, it is of of said head,

a Y e em-- at 10 to receive bolts 11 whereby they may be adjustedvertically to permit the forward end of the frame to approach nearer tothe ground or to be raised above the same ac-.

cording as these runners are adjusted. The entire frame'rocks over thepivots or hinges 6, and its forward end is supported by'the runners 8;and the frontend of the frame carries a scraper or plow 12 by meanswhich'the snow, ice, or other material'is taken ofi' of the surface ofthe ground or dug out f it. When the machine is being driven orpropelled from point to point and it is not desired that this plow shallwork,

the rear end'of the frame 7 is depressed onto the main beam 1 or otherframework of'the .vehicle by anyv suitable mechanism, herein shown as acable 1?,v which is led downward and around suitable pulleys 14 whenceit passes to the rear and is carried over a windlass 15 which standsadjacent the'drivers seat 16, the latter being supported by a framework-17 rising from the rear end of the beam 1. When this Windlass vis turnedin the proper direction to wind up on the cable 13, the rear end of theframe is depressed and its forward end is raised so that I the runners 8no longer contact with the ground and the plow 12- is lifted entirelyout of engagement therewith. On the other hand, when the tension on thecable is relaxed, the plow drops into working positionas'shown in Fig.1.

. The elevating'mechanism is carried by the f rocking frame 7 and itcomprises a trough,

and an elevator and presser moving upward therethrough. Beams 20 aresecured at their lower ends to the frame 7 and are mounted at theirrearupper ends on standards 21 rising from the same frame 7 and thetrough consists of a floor 24 and sides 22 carried y said beams; Atpoints near. their upper l lower ends said sides are provided withartshaped slots 23 for a purpose yetto appear.

The elevator is of the ordinary endless type, comprising-chains 25 ateach side cong,

' vnected by. suitable slats 26which pass over ,.the floor -24 of thetrough the chains, running over-sprocket wheels 27 and 28 at theextremities of the elevator as usual and the return or lower side of;this endless belt run-.

ning downward'beneath' the trough floor asv seen inFig. 1. v vator andis in'efiect anotherendless carrier mounted in a frame 30 of it's-own,the frame being of a v proper' size to fit movably be. tween the sides22 of'the trough and by prefv erence havingan extension 31 hingedly'connected to its front end by a rule joint 32 so that the extensionprojects forwardly and: downwardly beyond thefront end of the ele-.vator, whereas the rearend of-the'frame 30" is not carried upward asfar. as the frame ofsaid elevator. The endless carrier form ing part ofthe presser is composed of a pair The presser overlies the eleof chains35 connected by slats 36, the moving around sprocket wheels 37' and 38'Whose shafts are journaled in the frame 30 at its upper end and in theextension-31 at 1 its lower end, and theslats are provided with spurs 33or brushes 34 or both for a purpose to appear. a 4

The motive power for actuating the eleating mechanism is herein shownas'a' gasolene engine E whose controls are within reach of the operatorsittingonthe seat 16 and need not be described; and power from saldmotoris conveyed in any suitablemanner to a shaft 40 which is journaledthrough i the frame 20 'of the trough and carries at so each end a pairof sprocket-wheels 41 and 42. Each sp-rocket wheel 41 is connected by achain belt 43 with a sprocket 44 fastion" i the upper shaft 49 of thepresser, and each Y sprocket wheel 42 on the shaft-40 is connected by 'atwisted belt 45 with a.'sprocket wheel 46 fast on the upper shaft of'theele- 0 va tor. Therefore when power is conveyed from the motor E throughsuitable clutches or other connections to the shaft 40,; the '90sprocket wheels 41 and 42 thereon drive thevelevator and the presser inthe proper direction to cause their adjacent sides to move p r y inparallelism and preferabl the same speed" h pper shaft 49 of the pressergasses through a slot 50 in afbracket 51 sim within an at each side ofthe trough.

possibly to embed the same if the machine were used for scraping updirt, or in other ways well understood by those familiar with this art.
